Every pool deck is a different material
Kool deck, pavers, travertine, stamped concrete and plain broom finish all take different pressure. Kool deck in particular will strip under a wand and cannot be spot-repaired invisibly.
Keeping it out of the water
Run-off is directed away and the pool is covered or the chemistry is checked afterwards. A deck wash that dumps detergent into the pool creates a second problem for somebody else to solve.
Coping and tile
The calcium line at the tile is chemistry, not dirt, and it does not come off with pressure. We will tell you what will and what needs a different treatment.
Tell us about the surfaces. Somebody will come and look at them.
The chat takes the surfaces and the address, then hands it to the desk. It books quotes — it never prices a job in a chat window.
